Growling, gurgling and bubbling are usually ordinary sounds of digestion, caused by food, fluids and gas moving through the gut. The surrounding symptoms matter more than the noise itself.

If your stomach growls, gurgles, rumbles, squeaks or makes strange bubbling sounds throughout the day, the good news is that it’s usually a normal part of digestion. These noises are often caused by the movement of food, liquid and gas through the digestive tract. Hunger, digestion, swallowed air and gut bacteria can all contribute to the soundtrack coming from your stomach.
Most stomach noises are harmless. What matters is whether they’re accompanied by symptoms such as persistent pain, severe bloating, ongoing diarrhoea, constipation or unexplained weight loss.
The digestive system is constantly moving. As food travels through the stomach and intestines, muscles contract and relax in coordinated waves, pushing food, fluids and gas forward. These involuntary movements naturally create sounds.
Doctors even have a name for these noises: borborygmi. While the term sounds alarming, the phenomenon itself usually isn’t. In many cases, the sounds become more noticeable simply because the surrounding environment is quiet.
Ever notice your stomach seems loudest right before lunch or late at night? During hunger, the muscles of the stomach and small intestine are largely quiescent. When the stomach and small intestine are empty, they continue performing housekeeping contractions that sweep leftover food particles and digestive secretions through the digestive tract. These contractions can produce the classic growling or rumbling noises many people associate with hunger.
Ironically, the noise isn’t always the stomach demanding food. It’s often the digestive system cleaning up between meals.
Gas is another major reason the digestive system makes noise. Throughout the day, we swallow small amounts of air while eating, drinking, talking or chewing gum. At the same time, gut bacteria naturally ferment certain foods, producing gas as part of normal digestion. As gas moves through the intestines, it can create bubbling, gurgling or popping sounds.
Common contributors include eating too quickly, fizzy drinks, chewing gum, large meals, certain fermentable foods, consumption of foods that may lead to excess gas production and poor gas clearance such as broccoli, cauliflower, cabbage, corn, turnips, onions, peas, wheat, dairy, radishes, lentils, apples, pears, etc, or constipation, which can trap gas. Some added fibres, particularly inulin-type fibres, are also known to increase wind in some people.
A noisy stomach after a meal is often a sign that digestion is underway. As food enters the digestive system, muscle contractions increase to mix food with digestive juices and move it through the gut. This extra activity can make digestive sounds more noticeable. Meals that are especially large, rich or eaten quickly may sometimes amplify the effect.
The sound itself is usually less important than the symptoms around it. Occasional rumbling, gurgling and bubbling are normal. It may be worth paying closer attention if stomach noises are regularly accompanied by:
A noisy stomach alone is rarely a useful clue. A noisy stomach combined with recurring digestive symptoms may tell a more realistic story.
If stomach sounds are becoming disruptive or embarrassing, a few simple habits may help:
The goal isn’t to eliminate all stomach noises. A silent digestive system isn’t necessarily healthier. The goal is to understand what’s normal for your body.
The best question to ask isn’t “How do I stop this?” It’s: “What else is happening when my stomach makes noise?” Are you hungry? Have you been eating quickly? Are you feeling bloated? Did you have a fizzy drink? Have you been constipated for a few days? Context often provides more useful answers than the sound itself.
If today’s rumbling coincided with an unusually drowsy afternoon, “Why Do I Feel Sleepy and Heavy After Lunch?” might be worth a read. And if the noise has been showing up alongside hunger that returns suspiciously fast, “Why Do I Feel Hungry Again So Soon After Eating?” covers that pattern.
Instead of guessing, try asking:
“My stomach has been making loud gurgling noises for the last few days. I also feel bloated after lunch and tend to eat quickly. What are some possible reasons, and what patterns should I pay attention to?”
The more context you provide about your meals, symptoms, routine and timing, the easier it becomes to spot patterns.
Noticed any tummy rumbling today? That’s worth a quick note, on its own it usually means nothing, but the pattern over a few days is where the useful information lives.
Is it normal for my stomach to make noise all the time?
Yes, for most people. Frequent stomach noise, or borborygmi, is usually just digestion and gas moving through the gut, and it tends to be more noticeable in quiet environments. It’s only worth a closer look if it’s regularly paired with pain, bloating, or changes in bowel habits.
Can stress make my stomach noisier?
It can. Stress causes cortisol hormones to rise, which reduces digestive enzyme secretion as well as affects gut motility. It can speed up or slow the gut, disrupt the digestion process, and heighten how strongly digestive sensations are felt, which sometimes means more noticeable rumbling or gurgling during stressful periods, even without anything unusual happening with food.
Should I be worried if my stomach is loud but I have no other symptoms?
Generally, no. A noisy stomach with no other symptoms is usually just a sign that digestion is working as expected. The sound on its own isn’t a reliable indicator of anything being wrong.
A noisy stomach is usually a sign that digestion is happening exactly as it should. Hunger, muscle contractions, food movement and gas all contribute to the sounds you hear.
What’s more important than the noise itself is the pattern around it. If stomach sounds occur alongside recurring digestive symptoms, tracking those symptoms can provide useful clues.
Note: If symptoms continue, are severe, or keep coming back, it’s worth speaking to a doctor. Sudden weight loss, blood in stool, severe or persistent pain, or difficulty swallowing need prompt medical attention.
